To equip participants with the knowledge to identify and recognize characteristics that render bearings unserviceable and/or unacceptable upon engine operation. Participant will learn the basics of failure analysis identification and the probablecauses of failures. Participant will also be informed of the cleanliness requirements for the oil lubrication system and will be taught proper handling and installation techniques, methods, and practices to minimize the opportunity for premature bearing failures.
